Extracts the manual-redirect/per-hop-revalidation/timeout loop from
fetchHtml into a shared fetchWithRedirectGuard, exports isPublicHttpUrl,
and adds fetchIconBytes() -- an image-content-type-gated, 1MB-capped
byte fetch reusing the same SSRF guard as the existing HTML discovery
path. discoverFavoriteIconUrl behavior is unchanged.
Prepares the fix for favicon hotlinks breaking on sites that send
Cross-Origin-Resource-Policy: same-origin (e.g. claude.ai) -- Tessera
will proxy the bytes through its own origin instead.

- CR-01: fix SSRF bypass — isPrivateIpv6 now delegates ::ffff:<ipv4> to
isPrivateIpv4, covering 172.16-31.x and 169.254.x ranges
- CR-02: add ParseUUIDPipe to GET /favorites widgetId param + service guard
